Correction analysis method according to joint non-bone modeling partition volume ratio

The invention belongs to the technical field of lower limb correction, and discloses a correction analysis method according to joint non-bone modeling partition volume ratio, which comprises the following steps: S1, acquiring lower limb data of people with normal lower limbs, three-dimensionally reconstructing a normal lower limb model, and establishing a lower limb model database; S2, acquiring lower limb data of the comparison individual, and obtaining a comparison lower limb model after three-dimensional reconstruction; S3, selecting a normal lower limb model with the highest matching degree from a lower limb model database according to the three-dimensional reconstruction data of the lower limb model to obtain a matched lower limb model; S4, comparing and analyzing the lower limb modeland the matched lower limb model to obtain a lower limb skeleton deviation angle of the compared lower limb model and the matched lower limb model; S5, adjusting the position of the thighbone or thetibia in the comparison lo
